Man that taping flex arm is awesome! I’ve never seen one of those. Don’t know if you remember but many years back when your channel was just getting going, I needed some help and you made 2 hydraulic cylinder rams for my case backhoe support legs, you taped the ends of the rods and chamfered the other side so I could weld my eyelets on and shipped them to me here in California. I still have that tractor as it was my grand dads, and was handed down to me. Been watching your channel ever sense as I “play” machinist with a smithy granite 1340. Your always so helpful and explain things so it’s easy to understand. I wish I had the knowledge and experience you got as a machinist. Keep up the good work! Jeremy
I have ‘one off’ parts that I need for my farm and tractors at least once a month. There is not a single machinist in this area willing to do ‘one off’s’ at any price. I ended up watching every one of your videos from the beginning, buying a basic lathe and have saved at least $50k over the past five years! Since the supply chain and inflation issues came up I find I’m not only doing for myself but many of my farmer neighbors as well. Thanks for great content, great advice and the patience needed to walk us beginners through this trade so that we can get professional results every time! You’re a prince!
I love farmers. Self-reliance and resourcefulness exemplified. Thanks for sharing - made my day.
Man that sucks my machine shop does basically nothing but one offs, I do work for farmers all the time around here. Its crazy what you can make with some knowledge and basic equipment
Try the local high school.
Where I live here in Oklahoma all machine shops are either CNC shops or engine shops, so I bought a 104 year old L&S lathe a Brown and Sharp horizontal #0 mill and a Summit universal mill enrolled in the machine shop class at my local votech I plan on opening a job shop once I finish the course
My son and I have learned a LOT from your channel.
Adam, what I respect most is how find a balance between giving ear to constructive ideas shared with you, but you don't let the harsh, childish comments get to you. Good job for staying positive. There's WAY more fans than haters. Keep up the good work!!
"We've got a machine shop, so we can do better." Nice!
That's where your buddy Abom comes into play!
In my company, we believe in “being your own engineer”. Meaning, don’t let equipment slow you down, make your best shot at a fix, and get to it. Gotta trust yourself and don’t listen to the voices LOL. I sure wish I had a nicely equipped shop to make fixes like this!
You know, I have always been amazed at the amount of knowledge you have in regard to the intricacies of machining and everyday mechanical application. What I wouldn't give to apprentice under you. You are what America is made of, keep kickn ass brother!
For the hitch, the two bolts that hold it to the shank are supposed to be torqued to 250lb-ft after you've set your angle adjust and adjust set screw. It locks everything together. They should also have those cup (belleville) washers on both sides, top and bottom.
Just to add, the above info should be in the manufacturer's install manual. If you had the RV dealer do your hitch install, I'd get ahold of that manual and do it yourself and check the torques on all of it. I'd put good money on them having done none of it properly.
Bump this up hopefully. Had to re-set up an installation for a friend after his rv dealer undertorqued those cross bolts and his moved around.
Love that heavy knurl. One of my favorite things to do in an engine lathe.
WHAT WAS THE KNURLED STAINLESS FOR???
I was thinking the same thing
R&N Taps...made 1 block from my shop...my father worked there for 30+ years...
Hell yeah we can abom it you abom it it last forever
Things made by a man that is a master of the machine that makes all. And the shapper video I watched. Dad's was made from a flat belt unit with twists to the action. Thank you
If you put a longer set screw on that tow bar, you could fit it with a lock nut.
I think that slot is the major problem. Bushings and eliminate the slot and it should take out most of the play.
Adam, you might machine a 150-degree cone shape on the face of the set screw to keep the pressure on the point. With a flat on the end of the screw, and the face not sitting parallel to the pad, any movement will loosen the screw. Same thing on the top screw that you need the screwdriver for, especially with all the surface area on the face.
Watching you is like being at my old job and hanging out with the maintenance guys in the machine shop. Always friendly and always ALWAYS! willing to teach a man the right way. I commend you. Happy holidays and I wish you another great year that I will hopefully still be around for.
Cool show. Like the tractor! We love ours and they are tough and will run forever.
You will love the small Kubota tractor. I have pushed mine well past it’s limits on several occasions. It is a work horse. I couldn’t have done a 1/4 of the stuff on the farm and shop without it.
The head on your hitch is angle adjustable to set the tension bar angle. It's not an arbitrary adjustment. the bolts are supposed to be able to move around in the holes to provide clearance to adjust the angle. Torque the bolts to spec. Try reading the manual.
Right, the one I had set up, those cross bolts were torqued to 250lbs/ft. Those conical washers with the teeth crush in and pinch that whole thing tight. Check the hitch setup manual.
I guess Happy New Year is in order now. Hope you enjoy the tractor and I look forward to adventures at the new shop and the new property. Greg
Merry Christmas. Love those vertex drills, Ive never seen those before
Well done and a Happy New Year to you and Abby and many thanks for the years thats passed
Congratulations on the tractor! Very wise choice.
You might want to use a longer bolt with a lock nut for the adjuster.
Nice video Adam. You and Mrs. look extremely happy, like kids in a toy store. Merry Christmas and Happy New Year.
Awesome stuff Adam! That is a sweet little Kubota too!
Congratulations on your tractor purchase!
Tractor is awesome! Very nice.
Good hint on marking the pipe tap. Thanks.
I like that U-bolt mod, good idea on a receiver hitch! Nice tractor!👍
Congrats on the new tractor!!!!
Had a very similar head on our tow rig when I was crew chief on a race car that had the same problem. It would not stay tight. We fixed it... with a welder. Sure we gave up the adjustment but after you have it set you don't want to move anyway. :-D
Congrats! I just bought a new Kubota L4060 and I love it. So many things it can do to make work easier.
Love watching your work
personally Adam I think the guys who manufacture the trailer components are the same guys who make train couplers as well with a whole bunch of slop
That 45/64ths bit you drilled with cuts super evenly, I seem to always have to work on mine to get them to cut on both flutes evenly.
A quick tip for the ramps on your trailer. Put some witness marks on the short beavertail part of the trailer deck for where the ramps line up. I used different color paint for each different item that I loaded. Orange for the Kubota, red for the SXS, yellow for the zero-turn mower and so forth. That way you know where to set the ramps compared to the width of the machine you are loading. Merry Christmas Adam & Abbey.
Great idea man!
Hey Abom 79, Happy Year 2022 and may it be the best year for all of us. hug
Hey Adam, I just want you to know that your videos/content has inspired me a great deal. I went to school for machine tool and die 18 years ago and I ended up in the HVAC-R industry instead. I've always been passionate about machine Tool & Die or Machining in general but it was largely to do with your home workshop and content that's inspired me to purchase and set up a bridgeport mill and now a clausing lathe in my garage. I've done some projects on the mill and I love it. The lathe needs some parts made for it before it can be used ( cross slide and top slide, along with the tail stock quill and other odds and ends) but I have a good deal of respect for you and I truly hope you know how many lives you touch and impact in a positive way with your content on a daily basis.
Congratulations on your new a year ago tractor ! Well earned. 🍻
That's a nice looking tractor. Greetings from Arizona.
I see your getting ready to clear up the land you purchased exciting times
Chattanooga is great for camping, one of the best parts about living here.
Merry Christmas to you and Abby.
Four cone washers. So as you tighten the two bolts the cones jam in to remove all the slop
Excellent content and video production. Great job Adam. Happy New Year!
Hello from Finland! Nice video again and Merry Christmas to whole family. Kubota looks great!
The two large squeeze bolts should lock that up after you set the cant angle with the top and bottom jam screws. Don't know about that Reese, but my equalizer Hitch has a torque spec on those large two fasteners of 320 ft lbs. Yes, 320. That requires a 3/4" socket drive 1-1/8" socket, and a 48" long torque wrench to set properly. I suspect your problem may involve not tightening those bolts enough.
Hey big man, I hope you and family had a great xmas. Loads of fun and laughs like mine, catching up with family is always fun. It's chaos with everyone around but so much fun... family is the best.
Wishing you and family the very best for the new year, you have a good one
Dovetail joint, you'll never get backlash.
With that you can do a wedge bolt assembly 2 wedges one from top one from bottom of gap pull togather with a bolt that won't loosen up.
But if the bolt holes were like the ways of a mill slid up and down, a bolt could adjust the height and its not going to get slack or loosen up.
New tractor! You can make so many attachments!!
Congrats on your new tractor!!!!
Merry Christmas! God bless!
congrats on the new perches Adam
Equil-i-zer dampens sway. Take a serious look at this system. I'm absolutely sure it saved my trailer/tow rig on a very windy trip in Idaho.
Happy New Year to you both. This was another very entertaining and informative video. Enjoyed the machining and repair of the hitch. That Kubota LA525 is super! The 3-cyl 36.6 hp Kubota engine is a great machine. That tractor will serve you very well, I'm sure. Thanks for sharing all this with us.
A second fix that would go on the 3/4" bolt that has the slot I've seen myself but I don't know if I'm going to be able to describe it properly so aplogies in advance. We had something similar on one ship where the mount came adjustable but once adjusted stayed that way forever. Like you it always vibrated loose. Our machinist made up a washer that was flat on the bolt side but had a raised, curved piece on the back side that exactly matched the slot. This raised piece was the thickness of the slot metal minus clearance. We assembled the mount in the correct position then used a transfer punch to mark the centre of the bolt line and drilled out the hole to a tight clearance fit. There was two of these washers.The new washers were essentially curved bushes that fitted in the slot. I wish I could upload pictures here, I could draw it and it would make a lot more sense. Best of luck with the hitch, I know exactly what you're talking about having the hitch slop making the drive uncomfortable.
Congrats on everything man. And appreciate the motivation bro 👍🏼
Drill the head of your set screw and safety wire it.
That tractor is pretty sweet. Great video.
Great job on that hitch
Thank you Adam I enjoy watching your wonderful videos and merry Christmas thank you for sharing I am watching from South Africa
yes he needs loading stands, or ramps with stands built in and blocks between both tires on the trailer
Last thing needed is when loading the surge lifting the trailer off the ball and running it into the back side of the truck or damaging the transmission
When we load we usually have someone holding the breaks on the truck to to control the surge when the tractor hits the trailer, Though we load machines that weigh a bit more
Congrats on that Kubota! Fine looking machine.
you could always make dogbone metal gasket with square ends and bend the corners up to lock bolts down, engine builders use them in some rebuilds to keep bolts from loosening
I've got the same hitch. I sleeved the bolts and welded the set screws
Merry Christmas Adam and Abby.
You will like that Kubota. Good video.
Great video as always Adam. As far as boring the 3/4" (.790" as you mentioned) holes and bushing them you might want to get metric grade 10.9 bolts in 20mm. The diameter of them is .787". Boring the bracket holes to .875" or 1.000" could possibly weaken the bracket.
We use a Reese hitch system on our camper....and it's no better slop-wise. It drives me nuts! Time to fire up the lathe in pops shop and make it tight/right. Some folks don't understand that throwing money at it doesn't always make it better.
"We have a machine shop. We can do better." No doubt your grandfather's and father's words coming out of your mouth. Nice work, Adam!
Best SNS seen in longggg time!
Might go back with grade 8 bolts in the trailer hitch. Great video
You can also cross drill the bolt head and use a small hair pin to stop it rotating
for your toe hitch, what about 2 wedges from top and bottom and a long bolt clearances through the top one and screwed into the bottom wedge with a washer and split pin through the end to prevent anything falling off per chance.
Adam, rather than bore out the forging for bushes, why not just use 20mm dia bolts? You measured the existing holes in the forging as 0.790”, which is 20.07mm. It is not as if the bolts have to be touched again once they are installed, and in any case, you would have the right spanner.
More importantly, the other thing that I would do is make the thickest shim packer possible to go at the side of the forging, so that the aft piece can be made to clamp to the sides of the forging when the bolts are fully tightened. The bigger metric bolts would give some extra clamping capability or you could even go to a grade 12.9 socket head cap screws for even more clamping force. That should achieve a rigid friction-grip joint between the aft piece and the sides of the forging, which would make the cack-handed grub screw arrangement redundant. If the sides of the forging are a bit too irregular, you could skim it in the milling machine to improve the fit with the aft piece and the shim packer. Cheers
I also had the thought of drilling a hole through the square headed bolt and running a safety wire through it and around the plate. That would keep it from loosening up.
I used to make thousands of these in 316. Drill , tap, face and chamfer. Back face and chamfer.
Why are they not in stock...you had hollidays^^
@@KnocclHead Chinese container ships can't leave port ?
ahh your right, but still this three here are made in USA..
Thank you this medication. Dad has passed. But he was good and loved doing his own repairs. He would have a Allen bolt and or a lock nut in the hole maybe a thined lock not.
The anti rattle clamp is great!
If you drill a hole through the head of the bolt, you could use a split pin or locking wire to stop it from coming loose, just a thought, love the vids.
Merry Christmas from NE Ohio,thanks for another great video.🤗😎🤗😎
That hitch. Those do loosen up. Mine was bolted like that, but once level with the truck, it was fully welded.
I like the antirattle you made. Seen those before. I'll have to make one for myself.
make your on bolts like aircraft with shaft through all of hitch holes, and washer for fit. you have all the skill and a machine shop. got video.
the knurling is beautiful
You could make a wedge to drop in the trailer hitch from the top, it would just keep falling down in to take up the slack.
Those knurls were beautiful.
Merry Christmas to you and your family!
Adam, half the fun of watching your videos is reading the comments from people like Dave Fuelling & all the "superior intellect" types that were absolutely certain your anti-rattle clamp would never work. Doesn't matter where you are, the crowd is ALWAYS certain that you are doing it the wrong way & that any new idea is bound to fail. Been working for an UDW subsea engineering company that takes on the jobs the big petroleum engineering firms refuse to touch because "there's no way to make that better" for the last 10 years & your comments section sounds just like some of the initial project meetings I have attended there.
Steve, I believe they’re the same “superior intellects” on all TH-cam machining sites, at least it seems like the same number of them. I know there’s more than one way to skin a cat but some people believe that their way is the only way. Lol
i just bought the same tractor last year youll like it. only tip i have for you is if it has to regen dont freak out cause it takes forever to regen if you get lucky it regen while your working but i just finished using mine one day and it decided it needed regened and had to sit there for 20 30 minutes at 2700 rpm while it regened. try to keep the rpms above 2500 when your using it and it wont regen as often mine did its first regen at about 45 hours also look into getting the tires fluid filled with rimguard its beet juice its non corrosive and adds alot of weight to the back about 300lbs per tire if i remeber right
You may fall in love that tractor, I sure did. However the front tire sidewalls gave way, so I went with Carlyle brand. Much heavier duty for fork-lift operation. Quick detach is the bomb for Booth!🙏🥳🇺🇲
I think those vortex drill bits work great in thin sheet metal :)
Happy New Year. I suggest replacing the square headed set screw with a longer one then use a jam nut to keep it from backing out.
I love my Vortec drill bit set also!😀
You could stack a few disk springs inside that washer you made, so that whenever the bolt gets loose the washers will keep up the tension.
Big New Toy, nice ! Right, like, I wasn't jealous before....
But hey, thank you as always, and Merry Christmas !
Uh oh Adam got a new tractor, we can find all kinds of trouble to get into now. 😂 Congratulations and Happy New Year to you and Abby.
Looks like you are ready to move some SNOW! LOL
I figured Adam would have shopped around for a used Kubota...like all of his machines ! LOL. Nice to have...always !
Watch pulling into the shop. Roll bars to tall for your 7' door it looks like its 9 foot tall.
I've put car steros in that brand tractor with the cab on them lot of fun to drive wished I had one with the excavator and bucket on it. Very handy.
What did I miss about what the knurled rods for?
SNS on Christmas!? What a fantastic gift 😃
